80% VOO and 20% AVUV

I M24 have around 80k to invest and been on this on this reddit for some research. I have other investments too but want to relocate to VOO and others.

Is this split 80% VOO and 20% AVUV good? Or just go 100% on VOO. Or something else for the 20%?

Also what are the thoughts on QQQM and similar stuff at my age?
